Release notes: https://github.com/opencontainers/runc/releases/tag/v1.1.3 In particular, this one is important: * Retry on dbus disconnect logic in libcontainer/cgroups/systemd now works as intended; this fix does not affect runc binary itself but is important for libcontainer users such as Kubernetes.
